Apache Qpid Proton-Dotnet: Apache Qpid Proton-Dotnet: Denial of Service via unbounded type nesting
A pre-authentication attacker could leverage type nesting to cause a StackOverflowError potentially leading to denial of service.
This issue affects Apache Qpid Proton-Dotnet through 1.0.0.
Users are recommended to upgrade to version 1.1.0, which fixes the issue
A flaw was found in Apache Qpid Proton-Dotnet. This vulnerability allows a remote attacker, without needing to authenticate, to exploit a weakness in how the software handles data structures with excessive nesting. This can lead to a StackOverflowError, which ultimately results in a denial of service (DoS), making the system unresponsive or unavailable.
